John,
I got mine squared away. It was my starter. I had a spare and both were shot. One had broken magnets and the other had worn brushes. I took the two and made one. It cranks properly now. I was looking everywhere else because I couldn't see me having two bad starters. If higher CCA helps yours, I would start to suspect a poor connection. Putting a car battery on mine did seem to help but it still wasn't cranking right. I would suspect your timing is correct but worth checking. Your compression release is another likely cause. I really don't think the battery is your issue if it cranks others engines, even a 10 hp. There's 4 brushes in the starter. I was working with two. Now all 4 are good and my cheap Advance Auto (375 CCA battery if I recall correctly) battery even with a poor charge does well.
Start a thread. It will be running properly with everyones advice. If you have the ability, open the starter and check the magnets and brushes. It's not as daunting as I thought.
Good luck.
